Where does public bus stop from town to airport?

[finy]

I keep seeing a big white bus driving along Utarakit Rd and it says airport on it.

I need to get to airport on Friday and was wondering if anyone could point out where I can jump on this bus in town?

Thanks

At the bus terminal in Talat Kao

In December I took the bus from Ao Nong to the Krabi airport. A few people got on and off it along the way. But I couldn't reconstruct the route in my head.

For anyone interested the pickup point is outside Chao Fah VAlley Bungalows on Chao Fah Rd.

I think the times are 12pm, 1pm, 2pm (this is what I was told because my flight is at 3) but the last bus is at 5pm and there is one at 10.30 am I think.

Price is 90bht.
